The Green Super Chew Smooth offers a solid and smooth surface for practicing biting and chewing skills. If a child demonstrates oral defensiveness or sensitivity to touch and textures, the smooth bitable stem of the green Super Chew may be more readily accepted than the Red Super Chew. The closed loop handle is easily grasped by little fingers. Great for those seeking additional proprioceptive input into the jaw. The Green Super Chew features a bitable stem size of 1/2″ outside diameter. Individuals with autism require professional supervision when using these.
